The promoting effect of electromagnetic field (EMF) on biosynthesis and activity of extracellular proteinase and lectin in B. subtilis 316 M was observed. It caused 1.5- and 4-fold increase of the metabolites yield respectively. The EMF stimulated a 2-fold activation of lectin, rise of the enzyme activity and a shift of it pI from 11.4-11.5 to 9.2-9.3.

Compounds having hexagonal tungsten oxides (HTO) topology are of intense research interests owing to their potential functional properties, such as nonlinear optical (NLO) performances. However, most of the reported HTO-type compounds exhibit narrow optical bandgaps because of the d-d electronic transition of compositional d transition metals and lone pair electrons effect of Se/Te, which hinder their applications in the high-energy field, such as deep-ultraviolet (deep-UV) region. In this work, a new fluorophosphate, (NH)[ScF(PO)](POF) exhibiting HTO-topological structures is reported.

Dual-band tungsten oxide (WO) electrochromic films are extensively investigated, yet challenges persist regarding complex fabrication processes and limited cyclic stability. In this paper, a novel approach to prepare graphdiyne quantum dots (GDQDs) doped WO films with a hexagonal crystal structure, is presented. Structural characterization reveals that the GDQDs/WO possesses a coral-like, loose structure with high crystallinity due to the synergistic modulation of morphology and crystallinity.

Owing to its high sensitivity, surface-enhanced Raman scattering (SERS) has immense potential for the identification of lung cancer from the variation in volatile biomarkers in the exhaled gas. However, two prevailing factors limit the application of SERS: 1) the adsorption of target molecules into SERS hotspots and 2) the detection specificity in multiple interference environments. To improve the density of the SERS hotspots, 3D Au@Ag-Au particles are prepared in a porous nanoframes (PPFs) based plasmonic structure, which facilitated a richer local electromagnetic field distribution among the Au nanocubic (NC) cores, Au-Ag porous nanoframes, and Au nanoparticles, thereby promoting the adsorption probability of gaseous aldehydes into the hotspots.

In recent years, the modulation of brain neural activity by applied electromagnetic fields has become a hot spot in neuroscience research. Transcranial direct current stimulation (tDCS) and transcranial alternating current stimulation (tACS) are two common non-invasive neuromodulation techniques. However, conventional tACS has limited stimulation effects in the deeper parts of the brain.

Metal single atoms (SA)-support interactions inherently exhibit significant electrochemical activity, demonstrating potential in energy catalysis. However, leveraging these interactions to modulate electronic properties and extend application fields is a formidable challenge, demanding in-depth understanding and quantitative control of atomic-scale interactions. Herein, in situ, off-axis electron holography technique is utilized to directly visualize the interactions between SAs and the graphene surface.
